Rose plant named ‘POULpm003’

ABSTRACT

A new garden rose plant of the hybrid tea class which has abundant, yellow flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical classification: Rosa hybrid.

Variety denomination: ‘POULpm003’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of gardenrose plant which originated from a controlled crossing between thefemale seed parent, an un-named seedling, and the male pollen parent,‘FRYjingo’, a non-patented rose variety. The two parents were crossedduring the summer of 1993 and the resulting seeds were planted in acontrolled environment in Fredensborg, Denmark. The new variety is named‘POULpm003’.

The new variety may be distinguished from its female seed parent, anun-named seedling, by the following combination of characteristics:

1. While the seed parent has an open flower size of 100-130 mm,‘POULpm003’ is 80 mm.

2. The seed parent has a higher average petal count than ‘POULpm003’.

The new variety may be distinguished from its male pollen parent,‘FRYjingo’ by the following combination of characteristics:

1. While the pollen parent has more orange and red pigment in the flowercolor than ‘POULpm003’.

2. The pollen parent has more of an uneven growth habit than‘POULpm003’.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

1. Uniform and abundant yellow flowers;

2. Vigorous, compact, and even growth when propagated as a budded roseand on its own roots;

3. Disease resistance.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventors, anddistinguish ‘Poulpm003’ from all other varieties of which we are aware.

As part of their rose development program, L. Pernille Olesen and MogensN. Olesen germinated the seeds from the aforementioned hybridizationduring winter of 1994 and conducted evaluations on the resultingseedlings in a controlled environment in Fredensborg, Denmark.

‘POULpm003’ was selected in the spring of 1994 by the inventors as asingle plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULpm003’ by traditional budding and rootedcuttings was first done by L. Pernille and Mogens N. Olesen in theirnursery in Fredensborg, Denmark in July, 1994. This initial and othersubsequent asexual propagations conducted in controlled environmentshave demonstrated that the characteristics of ‘POULpm003’ are true totype and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULpm003’, as observed in its growthin in a field nursery in Jackson County, Oreg. Observed plants are 3years of age, and were grown on Rosa multiflora understock. Colorreferences are made using The Royal Horticultural Society (London,England) Colour Chart, 1995, except where common terms of color areused.

For a comparison, several physical characteristics of the rose variety‘Wingold’, described and illustrated in U.S. Plant Pat. No. 12,739 datedJul. 2, 2002 are compared to ‘POULpm003’ in Chart 1.
